Over the past few years, I’ve become much more aware of the physical impact of my thoughts on my body, and started to really see how negative thoughts, especially ones that come in the middle of the night, seemed to flood me with uncomfortable physical sensations. Thoughts about what I’m doing wrong, or what someone else is doing wrong, what I don’t like, or what disturbs me, are not only making my relationships harder, they are actually attacks on my body. I also noticed that when I didn’t change those thoughts, I inevitably woke up feeling tired, stiff or sick.
“Angry, hostile thoughts bring about rapid heartbeat, a rise in blood pressure, and flushing of the face, among other changes. Anxious thoughts can also speed up the heart and raise blood pressure, as well as induce tremor of the hand, cold sweat, a knotted stomach, and a pervasive weakening, as when we say a person is “sick with dread.”
Different kinds of thoughts must produce chemical changes in the brain in order to account for such physical manifestations. To quote one researcher, “There is no twisted thought without a twisted molecule.”
Likewise, happy thoughts of all kinds, loving thoughts, thoughts of peace and tranquility, of compassion, friendliness, kindness, generosity, affection, warmth, and intimacy each produce a corresponding state of physiology via the flux of neurotransmitters and hormones in the central nervous system.
The profound physiological changes that happy thoughts induce lead to good health because the neuro-transmitters that mediate them in the body have a stimulating effect”. from Creating Health, by Deepak Chopra
